The apparatus shown in Fig. 1 comprises a furnace 10 in which are located parallel reaction tubes 16 surrounded by outer tubes 11 suspended from spring supporting means 12 connected to flanges 13 on the outer surfaces of the tubes.  Fluid impervious joints are provided by sealing rings 14 and asbestos packing rings 5.  The reaction tubes 16 are supported by welds 17 which join the tubes 11, 16 above the furnace arch 18.  The ends of the reaction tubes are closed by plates 19, 20.  Gases are supplied to the annular space formed between the tubes through inlets 39 and exhausted through a common offtake 23 having an adjustable pressure release valve 26 and a connection 27 to control mechanism 28.  Reactants are supplied to the tubes 11 through line 29 provided with a valve 30 in communication with the control 28 and the reacted gases are taken off through lines 34 communicating through control valve 35 with headers 33.  The ends of the tubes projecting beyond the furnace are enclosed in insulating jackets 36 and the tubes 16 are provided with expansion joints.  In operation non-combustive gases are flowed through the annular space between the tubes and the control mechanism is arranged so that on rupture of a reaction tube the pressure is stepped up in the annular space thus preventing escape of reaction gases; alternatively the control may operate the valves 30, 35 to shut down the plant.  In modifications, Figs. 2 and 3 (not shown) the outer tubes enclose only part of the inner tubes or may be extended to enclose the ends of the tubes.  The cross sections shown in Figs. 6-8 show modifications in which (6) three reaction tubes 110 are enclosed in a common outer tube 111 (7) the inner reaction tube 120 is supported in the outer tube by ribs 122 (8) the reaction tube is divided into sections by cross members 133.

Title: Improvements in or relating to electric impulse selecting mechanism
IPC: G04C13/00
Filed: 1939-10-09
Abstract: 536,368. Electromagnetic switches. SMITH & SONS (MOTOR ACCESSORIES), LTD., S., and RUSSELL, V.J.S. Oct. 9, 1939, No. 27550. [Class 38 (v)] A series of impulses delivered every half minute, say, to an electromagnet 11 causes impulses to be delivered at, say, every minute to a time recorder through mechanism involving the step by step downward movement of an arm 28 till a switch 25 is actuated, followed after a time delay by the return of the arm to its original position after which the cycle is repeated. The arm 28 which carries a mercury switch 25 controlling the impulses to the time recorder is pivoted at 27 and has a pin 29 which at the beginning of the cycle rests on a stop 21. Impulses to the magnet 11 cause the reciprocation of the armature 15 with its two arms 19, 20 and their series of stops 21, 22, 23, 24 which allows the pin 29 and the arm 28 to move step by step to the position shown in which the switch 25 is closed. This switch not only closes the circuit to the time recorder but also closes a circuit to two heaters 41 on bi-metallic strips 36 so that after a short time interval contacts 35 open and an electromagnet 34, previously short-circuited at 35, is energized and pulls up its armature 30 which lifts the arm 28 back to its original position, the magnet 34 then being de-energized and the pin 29 resting on stop 21 or 24 according to the position of the arm 15 The stops 21-24 are pivoted as shown to allow the passage of the arm 28 upwards.

Title: Means for automatically regulating the braking action applied to vehicles
IPC: B60W30/18
Filed: 1946-09-13
Abstract: 634,847. Vehicle brakes. TECALEMIT SOC. ANON. Sept. 13, 1946, No. 27591. Convention date, Sept. 14, 1945. [Class 103 (i)] To prevent the locking of vehicle wheels during a brake application or the continuance of locking if it occurs, unequal braking actions are applied to a pair of axles and are caused to react oppositely but normally equally upon controlling means for the brakes whereby the braking action is reduced if, due to the imminence of locking of the more intensely braked axle the braking action applied to it increases or if, due to actual skidding of the wheels of either axle, or both, the friction reaction thereon falls. As shown, the brake cylinder 16 applies brake-shoes 3, 4 to the wheels 1, 2 through linkwork, not shown, and the frictional drag of the shoes is transmitted through levers 7, 8 to act oppositely upon a rod 12 connected to a pair of brake cylinder exhaust valves 13, 14. The leverage is such that normally during a brake application the reaction on the rod 12 of the shoes is equal and opposite, but if the reaction of one shoe increases or decreases relatively to that of the other due to the imminence of locking of the shoe 4 to which the greater pressure is applied or due to skidding of either wheel, one or other of the valves 13, 14 is opened to reduce the brake pressure. The balance of forces acting on the rod 12 is also upset if both wheels skid, so that the frictional reaction on the wheels becomes equal. In a modification, the reactions of the shoes are transmitted by hydraulic master cylinders of unequal diameters to act oppositely on a common piston connected to the valves.

Title: Modular fuel rod spacer assembly
IPC: G21C3/356
Filed: 1971-06-14
Abstract: 1312739 Fuel elements UNITED NUCLEAR CORP 14 June 1971 [15 June 1970] 27811/71 Heading G6C A fuel rod spacer assembly comprises a cellular spacer for providing lateral support for the fuel rods of a fuel assembly intermediate the ends of the fuel rods, and a plurality of bearing clips for laterally spacing and longitudinally retaining the fuel rods in the cells of the spacer. Each bearing clip (Fig. 2) comprises a pair of resilient split rings 7, 8 embracing a fuel rod 6, a pair of linking members 14, 15 for joining the split rings 7, 8 together at their respective free ends, and means for releasably engaging the clip with the cellular spacer to prevent longitudinal displacement of the clip. The latter means may comprise spring tabs 17 on the upper edge of split ring 7 and the lower edge of split ring 8, located at positions about 90 degrees apart and adjacent pairs of bearing lands 11, 12. The lands 11, 12 are for resiliently engaging the cell walls of the spacer. Inward bends 13 in the split rings 7, 8 between the lands of each pair allow for the circulation of coolant and so prevent " hot spots " from developing in the regions of contact of the fuel rod 6 and dimples 10 formed in the split rings 7, 8 in the region of the lands. There are also dimples 10 adjacent the free ends of the split rings 7, 8. The linking members 14, 15 are made of a resilient material and are provided intermediate their ends with bearing sections 16 (for resiliently engaging the bearing sections of adjacent clips) extending radially outward beyond the peripheries of the split rings 7, 8. The bearing clips are assembled on to the individual fuel rods 6 by springing the clips slightly open so that the rods may be axially positioned without scraping against the dimples 10. The cellular (" egg-crate ") spacers are set up on their sides at the prescribed locations with their cells in alignment and the fuel rods with the bearing clips in place are passed longitudinally through the cells of the " foreign " spacers until each clip is positioned within the cell of its own particular " home " spacer. There is ample clearance for the passage of each of the clips if the rods bearing these clips are rotated 45 degrees about their longitudinal axes from their final positions in the fuel assembly. When in their correct longitudinal positions the rods are rotated back 45 degrees and snapped into position. Where there are four fuel rods in each cell of the spacer (Fig. 6), the bearing section 16 of the linking member 14 of each clip engages the bearing section 16 of the linking member 15 of an adjacent clip and the bearing lands 11, 12 engage the walls of the cell.

Abstract: 603,515. Control of A.C. motors ; electromagnetic switches. ENGLISH ELECTRIC CO., Ltd., and PEARSON, E. Oct. 22, 1945, No. 27818. [Classes 38 (iii) and 38 (v)] A starting device for an alternating-current motor having a starting and a running winding comprises an operating coil 1 which is connected in series with the running winding, two ferro-magnetic members 2 and 4 which are relatively movable and are arranged to separate when the coil 1 is energized, and switch contacts 5 and 9 which are operated by such movement to maintain the starting winding in circuit when the motor-current is above a predetermined value and to disconnect the starting winding when the motor current falls below that value. The ferro-magnetic member 2 carries a terminal block 3. The member 4 is mounted on a spring strip 6 which is provided with a copper disc 7 for eddy-current damping. A spring strip 8 carries the contact 9 which is adjustable relatively to the contact 5 by means of a cam 10. A bimetallic strip, 11, which is connected in series with the motor-running winding, mounts a contact 12 co-operating with a contact 13 on the strip 8 to afford an overload release. An auxiliary heater with or without a reflector may be placed near the strip 11 which may be so located as to be influenced by the temperature of the motor windings. The strip 6 can be bimetallic to increase the contactpressure between the members 5 and 9 when the strip carries current. The member 2 may be spring-mounted. The strip 11 may carry additional contacts to provide warning on overload. Preferably the coil 1 is provided with a casing of magnetic material which is dust-proof or allows for evacuation of air from the switch-working space or oil immersion of the working parts. The whole assembly may be built into or on to a suitable part of the motor, may form the motor terminal box, or may be disposed remotely from the motor.

Title: Computer Control of Chromatographs
IPC: G01N/
Filed: 1967-06-16
Abstract: 1,167,994. Controlling chromatographic separation processes. MOBIL OIL CORP. 16 June, 1967 [16 June, 1966], No. 27931/67. Headings B1X and B1L. [Also in Divisions Gl and G4] In the control and analysis of the output of a system of chromatographs in which detectors for each chromatograph produce analogue signals indicative of the quantity of a component eluted at any instant, these signals are supplied to a multiplexer and, after digital conversion, are processed in a digital computer which is also programmed to control the operation of the system. The components eluted from each column are detected by passing them over heated thermistors 25, 25', Fig. 2, connected, with reference thermistors 24, 24', in a bridge circuit, whose output is amplified before being supplied to the multiplexer. During the control process, the programmed scan by the computer of a list of periodic operations is interrupted every 1/10 second by pulses from a real time clock 20 to perform an analysis of the outputs from the detectors. The computer is programmed first to initiate the analogue to digital conversion of the signals from the detectors, then to correct them for any attentuation and store them. It also determines on what part of a peak each signal lies, i.e. whether it occurs at the start, maximum or end of a peak. At the end of each cycle of operation when all the components have eluted, the stored signals from the detectors are analysed. The area under each peak is calculated and the peak identified by comparison of its elution time with a table of ideal times, and its thermal co-efficient determined. The area of each peak is then divided by its thermal co-efficient and the quotients added. Finally the percentage concentration of each component is determined by dividing each individual quotient by the sum of the quotients. This data is then printed out on a tape, page printer or teletype unit.

Title: Stretching frame for stretching organic thermoplastic film
IPC: B29C55/08
Filed: 1962-07-20
Abstract: 941,358. Stretching films. LINDAUER DORNIER G.m.b.H. July 20, 1962 [Aug. 10, 1961], No. 27975/62. Heading B5B. [Also in Division D1] In a stretching frame for organic thermoplastic films, incorporating clip chains running in guide rails which are fixed to the web supports of the frame, and in which the width of the stretching zone may be adjusted by moving the web support, the ends of the guide rails, at points of transition between the stretching zone and adjoining heating, fixing or outlet zones in which the clip chains run parallel, are constructed as separate parts. Each part is arranged to be swingable on the web support about a spindle having its axis perpendicular to the chain path, and is arranged to be automatically adjustable. The bend that occurs in each chain path at the point between parallel and non-parallel parts of the guides is thereby rendered less abrupt. In a customary type of stretching frame (Fig. 1), the material B1 is fed into entry zone E, heated in zone A, stretched transversely in zone S, fixed in zone F and finally cooled to room temperature. The width of the stretching zone may be varied by altering the path of the clip chains from U1 K1, U2 to, e.g. U1<SP>1</SP>, K1<SP>1</SP>, U2<SP>1</SP>, in a known manner by use of handles H. According to the invention, the guide rails for the clip chains have the construction shown in Figs. 2 and 3 at the points of transition between parallel and non-parallel sections of the guides, e.g. U in Fig. 1. In one embodiment shown in Fig. 2, and, on larger scale, in Fig. 3, guide rails 1 and 2 of one zone and guide rails 5 and 6 of the next zone are rigidly fixed to the carriers of the stretching frame. The outer ends of these guide rails are constructed as separate swingable transition rails 3, 4, 7 and 8 which may be deflected laterally. The fixed rails 1, 2, 5 and 6 together with closure plates 10 and 11 are swingable about a spindle 9. In Fig. 3, transition rail 3 is shown swingable about spindle 13 whose axis lies in the line of vertical section of the associated rails 1 and 3. Transition rail 3 engages in the associated fixed rail 1 by means of a semicircular portion 16, and is cut off outside the semicircular portion 16 on the inside of the angle formed on deflection, obliquely to the path of the chain, whereas at the opposite side it is cut off perpendicular to the chain path. The arrangement is repeated in mirror image for transition rail 7. To limit deflection of transition rails 3 and 7, slots 15 and 15<SP>1</SP>, through which bolts 14 and 14<SP>1</SP> are inserted and screwed into transition rails 3 and 7, are provided in the support. The two swingable transition rails 3 and 7 automatically adjust to the required angle, and ensure satisfactory guidance and smooth movement of the clip chains over the transition point.
